**FastAPI** を使い始めたばかりの方は、とりあえずスキップした方がよいかもしれません。

Pythonでは、<a href="https://docs.python.org/3/reference/datamodel.html#context-managers" class="external-link" target="_blank">以下の２つのメソッドを持つクラスを作成する: `__enter__()`と`__exit__()`</a>ことでコンテキストマネージャを作成することができます。

また、依存関数の中で`with`や`async with`文を使用することによって`yield`を持つ **FastAPI** の依存関係の中でそれらを使用することができます:

```Python hl_lines="1 2 3 4 5 6 7 8 9 13"

interface could display a "Source" link that leads users to an archive
of the code.  There are many ways you could offer source, and different
solutions will be better for different programs; see section 13 for the
specific requirements.

  You should also get your employer (if you work as a programmer) or school,

## Version 5.0.0-alpha.4

_2022-02-01_

**This release introduces fast fallback to better support mixed IPv4+IPv6 networks.** Fast fallback
is what we're calling our implementation of Happy Eyeballs, [RFC 8305][rfc_8305]. With this

### Other notable changes

* Better compat with very old iptables (e.g. CentOS 6) ([#37594](https://github.com/kubernetes/kubernetes/pull/37594), [@thockin](https://github.com/thockin))

seccomp defaults, the kubelet uses the `RuntimeDefault` seccomp profile by default, rather than than `Unconfined`. This allows enhancing the default cluster wide workload security of the Kubernetes deployment. Security administrators will now sleep better knowing there is some security by default for the workloads.

To learn more about the feature, please refer to the official [seccomp tutorial](https://kubernetes.io/docs/tutorials/clusters/seccomp/#enable-the-use-of-runtimedefault-as-...

leads to Node goes `Not-ready` state when credentials for vCenter stored in a secret and Zones feature is in use. Zone labels setup moved to KCM component, kubelet skips this step during startup in such case. If credentials stored in cloud-provider config file as plaintext current behaviour does not change and no action required. For proper functioning `kube-system:vsphere-legacy-cloud-provider` should be allowed to update node object if vCenter credentials stored in secret and Zone feature used. ([...

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or
 - have a new beta version _(and deprecate the previous beta)_.
